• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sach ty) OR (sach tu)) lang ((ha hoi) OR (xa hoi)). hieu ve nuoc luc va thanh di cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sach ty) OR (sach tu)) lang ((ha hoi) or (xa hoi)). hieu ve nuoc luc va thanh di cua te~".
• Adding a wildcard symbol may retrieve word variants: vu ((sach ty) OR (sach tu)) lang ((ha hoi) or (xa hoi)). hieu ve nuoc luc va thanh di cua te*.
